Description Henrik Andersson cendio 2017-05-19 09:43:58 CEST 
When running FireFox within a ThinLinc session and creating a new tab, errors are logged into /var/log/messages.

Here follows a snippet of what is logged:

Comment 1 Henrik Andersson cendio 2017-05-19 09:45:45 CEST 
I have tried to reproduce the problem on CentOS 7 + FireFox 52.1.0 without success, however it is reproducible on RHEL7.

Customer reported that if SELinux is set in permissive mode, the problem goes away.
Comment 2 Pierre Ossman cendio 2017-05-23 12:58:43 CEST 
A first step is probably diagnosing the issue further. Is it a bug we should report to Red Hat? Can we do a work around?
Comment 4 Pierre Ossman cendio 2017-07-05 12:51:26 CEST 
This seems to have gone away when bug 6993 was fixed.
Comment 5 Pierre Ossman cendio 2017-07-06 15:25:20 CEST 
This has screwed up the test system in some way:

> libsepol.print_missing_requirements: thinlinc's global requirements were not met: type/attribute mozilla_plugin_t (No such file or directory).
> libsemanage.semanage_link_sandbox: Link packages failed (No such file or directory).
> semodule:  Failed!
